Dynamic or automatic balancing of rotating systems using a closed circumferential track around the rotating system that can accommodate different sized balance weights for different operating ranges

摘要

Device (510) for dynamic balancing of a rotating system (12) has at least one track housing a balance weight (522) that rotates within the track. The track forms a closed loop concentric to the axis of rotation (18) of the rotating system. Within the track there is at least one balance weight that rotates in at least one of the available track paths (546, 548, 550), which are continuous with each other.
